Lumped System Analysis: Quenching of Brass Balls

Please see the attached file for the fully formatted problem(s). A number of brass balls are to be quenched at a specific rate. The temperature of the balls after quenching and the rate at which heat neds to be removed from the water in order to keep its temperature constant are to be determined.
